Cairo, Egypt - May 3, 2007: Book of Osama Bin Laden in Cairo train station, Egypt. He was Most Wanted Terrorists and the founder of al-Qaeda global militant Islamist organization.

If a new media report is to be believed the late Al-Qaeda leader Osama Bin Laden’s son, Hamza Bin Laden, has married the daughter of Mohamed Atta, the leader of the hijackers who carried out the September 2011 terror attacks in the US.

“We have heard he has married the daughter of Mohammed Atta,” Ahmad al-Attas told the Guardian. “We’re not sure where he is, but it could be Afghanistan.”

The 29-year-old Hamza is Osama’s only son from his wife Khairiah Sabar who lived with him in a compound in Abbottabad, near a large Pakistani military base, when he shot dead during a US military raid on 2 May 2011. Notably, Bin Laden’s son Khalid was also killed in the Abbottabad raid, while his third son Saad was killed in a drone strike in Afghanistan in 2009.

Bin Laden’s brothers said they believed Hamza has been promoted to a senior position within Al-Qaeda and was aiming to avenge the death of his father by the US military. Considered as a deputy to the terrorist group’s current incumbent leader, Ayman al-Zawahiri, Hamza has made public statements calling out Al-Qaeda followers to wage war on the US, the UK, Israel, and France, including one in 2016 in which he vowed to avenge his father’s death.

The letters recovered and seized from Pakistan’s Abbottabad compound suggested Osama was grooming Hamza to replace him. Notably, Western intelligence agencies have been continuously keeping an eye on the whereabouts of Hamza over the past two years, considering him as a probable big looming threat.

Known as the Crown Prince of Terror, Hamza’s name has even been included in the U.S. Specially Designated Global Terrorist list.

After Laden’s death, his wives and surviving children have reportedly moved to Saudi Arabia, where they were given refuge by the former Crown Prince Mohammed bin Nayef.
